Abstract
A method of manufacturing a semiconductor device, in particular an integrated monolithic circuit, having a semiconductor body and comprising an insulation layer of insulating material, sunk locally into the semiconductor body from a surface of said body, into which a material is introduced of activation in the semiconductor material through at least a part of the surface situated next to the sunken insulation layer, so that a zone of a certain type of conductivity is formed since it is activated with the activation material and which contacts the an underlying semiconductor part having the same type of conductivity and, in the contact area, the zone extends down to a depth greater than that of the sunken insulation layer, characterized in that the activation material is presented to the aforesaid part of surface before the formation of the sunken insulation layer.
